That very same question was asked on the printing summit and it comes
down to a choice between a de facto standard and an open standard. Note
that when you use PAPI you will probably still use CUPS behind it, it's
a question about which API you target, not which spooler you use. Given
that Linux distributions are very concerned about their ability to
innovate it seems to me that an open standard is a better choice than
one that ties them down to one particular implementation. But instead of
speculating about that it's probably better to listen what the various
people on the desktop_printing list that work for distributions have to
say about the topic.
